Low-frequency fluctuations in external cavity semiconductor lasers: understanding based on a simple dynamical model
(Institute of Physics, 2001-08)
We investigate the dynamical origin of low-frequency fluctuations (LFFs) in external cavity semiconductor lasers by utilizing a simplified, three-dimensional model derived from the infinite-dimensional Lang-Kobayashi (LK) ...
Self-organization of coupled nonlinear oscillators
(EDP Sciences, 1998-12-01)
The effects of impurities introduced into a lattice of strongly coupled oscillators are studied. Contrary to our expectations, a single impurity can control the chaotic behavior of a long array of chaotic oscillators and ...
